plotData

plotData is a simple Java application that reads numerical data from a 2-column CSV file and generates a chart saved as an image (output.png).

How to Run

1. Prepare your data file

Ensure a file named data.csv exists in the same directory.

Example format:

  • Time,Velocity
  • 1,10
  • 2,15
  • 3,7
  • 4,20

2. Compile the project

Ensure you have Java installed. Open a terminal in the project directory and run:

javac *.java

3. Run the application

java Main

4. View the output

After running successfully, the chart will be saved as:

output.png

Open this file to view the generated chart.

Tips

  • Make sure data.csv is in the correct location
  • Check file permissions if access is denied
  • Ensure your CSV format matches what CsvReader expects

Notes

  • The output file (output.png) will be overwritten each time the program runs
  • Modify filename in Main.java if you want to use a different input file

TODO

  • read any .csv file not just data.csv
  • change output filename to {INPUT_FILENAME_WITHOUT_EXTENSION}_{YYYY.MM.DD HH:MM:SS}.png so the program can be run repeatedly
